` Be it known that we, Punten Lennox, Hrn'nn H. Romains, and Enwnni) HAYES, of Lynn, in the county of Essex,.and State of Massachusetts, liave invented a new and useful Improvement inMachines for Beaming Hides, as well as for scouring and Asleeking leather and do hereby declare the following to be a full, clear, and exact description thereof, due-reference being had te the accompanying drawings, making part of this speciication, and in whichi 4Figure 1 is a side elevation Figure 2 a plan,

Figure 3 arear' endv elevation of the said invention.

'This invention is an improvement in machines-for beaming hides or skins, or for scouring and sleeking leather, and relates to means for holding such hides in a manner to enable the Whole hide tob'e beamed or manipulated at one operation of the machine, in contradistinction to the mode shown in the machine constituting the subject of Letters Patent,No. -7O,2G8,Iand dated the 29th day of October, 1867, in tvhicll one-half only of the yhide is subjected at once the `action of the 'beaming-tool, necessitating the removal of the skin from the machine, and turning it about, endfo-r end. i u

Our present machine, .in its'generalcharacteristics, like the one before mentioned, is composed ofa reciprocating carriage or head, carrying a beaming-tool, and duly supportedu-pon a proper frame or standard, such reciprocating tool operating in connection with`a movable ear, for supporting the skin under the action of the the said cranks e e being balanced cranks.

tool, the car having a revolving orf lling movement imparted to it by theworli-man, as occasion requires.

Our invention consists in th'e-eiiployment` of a pressurbaror friction-brake, aliixed to the outer ends -of two levers, p'ivoted tothe opposite'sidcs of the supporting-slides of'thc beaming-tool carrier, and in advance of such carrier, and actuated by the driving-,power of thc machine, inisuch manner aste press uponthe hide with a powerful pressure, while the beamingtool is acting upon it,and hold it to the tablet upon which it rests, with i suiiicient power to prevent it from being displaced by the 'draught of the beaming-tool.

The invention further consists in a novel inode of applying the tool-carrier to its car springs, in mannerand for the purpose as lhereinafter explained. In the drawings above mentioned as illustrating our invention, the frame of the machine is shown 'at A, as composed of two upright twin standards, a q, each of such standards having a long horizontal extension, 65, projecting from its upper part, these extensions Z beingparallel to each other, and serving as`ways 01* guides to a sliding'carriage orA cross-l1ead, C, which is disposedbetween them, and so as to slide freely thereon, the necessary reciprocatingr rectilinear movements of such carriage being eil'ected by a con'necting-rod,l d, one end of' which is'pivoted to the carriage, and its opposite en'd t o a wrist-pin, a, connecting the two contiguous ends oi' two twin cranks, e e, which are supported at about their centres upon the inner extremities of two herijzontal shafts,j`f, duly supported in boxes y g, applied to the upper part of thel qmndards a a, before mentioned,

riage by means of The outer end of one of' the shafts ff carries fast and loose pulleys, it k. The sliding carriage c has four depending posts, z'z'z'z', upon .which is supported a plate, j, in such manner as to move freely up and down-upon such posts, a spiral spring, 7c', being coiled about each post 2.', the plurality of springs serving, by their extensions, t-o force the plate down with considerable force. i i

The beaming-tool carrier or head is shown at Z, as pivoted to the' under capable of longitudinal vibrations thereon, thesaid earriel` Zbeing as represented.

Furthermore, to the rear sid theoppositc end of s ueh rodvcarryingan cecentriclstrap, o,

side of the. plate j, and so as to be provided with a'boaming or ileshing-toohm, l

cof the tool-carrier Z`is pivoted one extremity of a curved eccentric-rod, et,

which encompasses an eccentric-block, p', applied 'fasse eccentrically to the wrist-pin a', before mentioned, the disposition of the eccentric-block p, with respect tothe cranks and the tool-carrier, being such that during a forward movement of the said tool-carrier, its beaming- 'toolshall bc raised into an angular position above the surface of the hide, and free from contact with it, and during a reverse or rearward movement of the tooljcarrier, it shall maintain the beaming-tool in van upright and rigid position, and by lowering its working-edge, bringv it forcibly in contact with the. surface of the hi'de.

As the operation of the beaming-tool upon 'the hide is well known, and has been described in Letters Patent before lreferred to, as granted to Lennox and' Roberts, further description of its action is not considered necessary.

We wish it to be understood that the present machine is to have 'applied to it, when in use, a movable car, for supporting the hide, constructed substantially as shown in Letters lPatentbefore mentioned, with the exceptiony that the revolving hide-supporting tablet of thel ear will be applied toits truck in nearly or quite an unyiclding, inflexible manner, in order to withstand the pressure of the clamp or brake,'to be hereinafter described..

l The effect of this brake is to hold thehide securely to the tablet during the manipulations of the beamingtool, and consists of a cross-bar, q, pivoted or otherwise applied to the lower ends of'two hanging arms, :c x, the upper ends of which are, in turn, pivoted to the outer extremities of two long vibrating-lere'rs, s s, pivoted to the outer sides of the guides b b, before mentioned, the fulera t t of suoli levers boing situated at about onethird their length from their outer ends, though in practice it may be found desirable to have this fulcrum an adjustable one, in order to vary the pressure of the ybrake upon the hide.

The opposite or inner ends of the levers s s rest upon the periphery of -two wipers, w w, fixed to the shafts fj', before referred to. l A

The form of these wipers, as shown in fig. 1 of the drawings, being the segment of about two-thirds of a circle, the dispositionof the plane portion, o, of the wipers, with'respeet to the leverss s and the beaming-tooll and its carrier, being such that during a forward movement of the .beaming-tool, the brake-bar 1 shall be raised above the surface of the`l1ide, and during the return movement of such beaming-tool, or while it is'scraping the hide,` the circular or longer portion of the wipers, acting upon` the levers s s, shall forcofthe brake down upon the hide with considerable pressure, and hold it firmly upon the operating-tablet of the car.

The levers s s are retained Iin contact with the peripheries of the wipers by means of coil-springs, or their equivalents, suitablyA connected with them and the frame of the machine.

The object of the before-described arrangement of the two cranks c c, supported upon the shafts'ff, and with the rods d and n, enclosed between them, is' to obtain great streng-th fparts, and an equal, steady motion of the machine, 'which lcould not be the case were the rods d and n applied to one crank, or to the face o'fa wheel.

The object in applying the tool-supporting plate or bracket j to the sliding carriage C, as described, is to allow of the necessary elasticity in the pressure of the beaming-tool upon the hide, for the reason, as before observed, that the'lremoval of this elastic feature from thehidc-supporting ear renders its .application to the tool necessary. l

By the employment of a brake or device for clamping the hide to the table, as described, the capacity of the machinefor labor is doubled, as thetime formerly occupied in reversing the hide, after one-half of it had been manipulated, is by this means saved 'and 'economized, as the entire circuit of the hide by the beaming-tool is accomplished without changing the position of the hide upon its tablet.

As the beaming-tool acts upon the hide from its centre, radially outwardduring the revolution ofthe tablet., such hide is treated in a more uniform and desirable manner than has heretofore been accomplished.

We claim as our invention, and desire to secure by Letters Patent of the United States, as follows:

1. In a machine for beaming hides or dressing leather, we claim a device so constructed and applied thereto as to automatically press upon or clamp the hide to its supporting-table, and hold it in position under the'acton of the beamingftool, in order to manipulate the hide at one operation. I

2. We claim, as a device for accomplishing the'abeve result, the combination and arrangement of the brake-bar g with the vibrating-levers s s, such leversbeing pivoted to the guides I: b, and actuated by the wipers u u, and operating in connection with the beaming-tool, essentially in manner and forv the purpose as herein shown and described.

3. We claim the mode of suspending the beaming-tool from the sliding-.carriage c, that is, by means ofthe plate or'bracket j, posts z' z', and springs c,"&e., substantially in manner and for the purpose as herein shown 'and described.

4'. We claim the arrangement or disposition of the twin cranks e c, as supported by thev shafts ff, and carrying between them thel two rods d and u, and eccentric, @essentially as herein set forth'and explained.
